There's a set available for pre-order at Rakuten Collectoys [ext link ]. The shop is seemingly Japan-only but they work international, too (I asked them about at and they offer direct international shipping via EMS). The shipping to Europe was calculated as 2200 yen EMS, which is about 0,7 kg.

Akira (4 years ago) #1388678Is not fair that only BiJ opened pre-orders for this set （；_・） I felt awful for that and because I was more slow than a snail with this cats ｡･ﾟﾟ･(>д<)･ﾟﾟ･｡
I realy hope these will be available off Rakuten or Mandarake after release.. TT
